As the title says, I've tried just about everything and I don't know what to do at this point. There is a distinctive noise and the fans only spin for half a second. Yesterday I did a test bench with just the heatsink, CPU, and GPU connected. It wouldn't power on at all with the GPU in so I took out the GPU and it powered on completely. So I assumed it was a GPU problem but it wasn't as I just bought a cheap one from Best Buy and still had the same exact problem.
